17011. Visual binary orbits and masses
ID:
ivo://CDS.VizieR/J/A+A/341/121
Title:
Visual binary orbits and masses
Short Name:
J/A+A/341/121
Date:
21 Oct 2021
Publisher:
CDS
Description:
The paper gives orbits and masses for some 200 nearby visual binaries, as derived from combining ground-based and Hipparcos data. Table 6 gives identifications and notes, and points to the detailed data in Table 1 (short-P systems with mass-ratio from the Hipparcos observations), Table 3 (mass-uncertainty below 10%) or Table 4 (mass-uncertainty above 10%).

Description:
The results of a BVR photometry observations are presented for multiple stars visual subsystems (table2.dat). The objects (table1.dat) were observed in 1996 with the 60 cm and 1 m telescopes at Maidanak Observatory (Uzbekistan) by aperture and scanning photometers. The positional parameters and physical relation of visual subsystems are also given (table4.dat).

Title:
Visual Double Stars in Hipparcos
Short Name:
I/260
Date:

Publisher:
CDS
Description:
This catalogue is the only complete list of all known double and multiple systems (18644) of which at least one component was identified in the Hipparcos final catalog in July 1997 (Cat. <I/239>), including the 2994 systems newly discovered by the satellite, as well as the 155 new astrometric orbital pairs also discovered by the satellite (Dommanget, 2000Obs...120..202D), and also the 38 new astrometric binaries components of known systems. It may be considered as a subset of the CCDM as existing in 1998 of which a first edition appeared in 1994 (Cat. <I/211>), and of which a second edition containing more than 45,000 systems is being prepared for publication. Consequently, the format of this list is that of the CCDM for which all information may be found in the introduction of its 1994 published version (as file I/211/ccdm.doc) The format of this catalogue is the same as the CCDM (Cat. <I/211>)

Description:
A total of 1000 new classifications are given for stars brighter than B=8.0mag in the Aitken double star catalog. The classifications supplement 865 classifications obtained in 1981 and 1984. Among the newly discovered stars are 12 new Ap stars, eight Lambda Bootis stars, one Ba II star, and 60 Am stars. A detailed list of the new classifications is given.
17016. Visual search for galaxies in the Galactic Plane
ID:
ivo://CDS.VizieR/J/MNRAS/277/125
Title:
Visual search for galaxies in the Galactic Plane
Short Name:
J/MNRAS/277/125
Date:
21 Oct 2021
Publisher:
CDS
Description:
We have visually examined 12 Palomar red plates for galaxies at low Galactic latitude b, where the Supergalactic Plane (SGP) is crossed by the Galactic Plane (GP), at Galactic longitude l~135deg. The catalogue consists of 2575 galaxy candidates, of which 462 have major axis diameter d>=0.8arcmin (uncorrected for extinction). Galaxy candidates can be identified down to |b|~0deg. One of our galaxy candidates (J24=Dwingeloo 1) has recently been discovered independently at 21cm by Kraan-Korteweg et al. as a nearby galaxy. Comparisons with structures seen in the IRAs and UGC catalogues are made. We compare the success rate of identifying galaxies using the IRAS Point Source Catalogue under different colour selection criteria. The criteria that require both the 60- and 100-{mu}m fluxes to be of high quality have the highest probability of selecting a galaxy (with d>=0.6arcmin), but at the expense of selecting a smaller number of galaxies in total.
17017. V,i,TiOr,CN photometry of And-II AGB stars

Title:
V,i,TiOr,CN photometry of And-II AGB stars
Short Name:
J/A+A/427/613
Date:

Publisher:
CDS
Description:
Our photometric survey of Local Group galaxies, using a four filter technique based on the method of Wing (1971, Proc. Conf. Late-Type Stars, ed. G.W. Lockwood and H.M. Dyck, KPNO Contribution 554, 145) allows the identification and subsequent characterization of their late-type stellar content. Two narrow band filters centred on molecular bands of TiO and CN allow us to distinguish between AGB stars of different chemistries [M-type (O-rich) and C-type (C-rich)]. The faint dwarf spheroidal galaxy And II, a member of the M 31 subgroup, was surveyed. From photometry in V and i as well as in the narrow band filters TiO and CN we were able to identify 7 new AGB carbon stars, to derive their mean absolute <Mi> and bolometric magnitude Mbol, their luminosity function, and their spatial distribution. We are unable to establish the true C/M ratio because the few M stars of And II are overwhelmed by foreground Galactic M st
17018. VJHK and SDSS photometry of DA white dwarfs
ID:
ivo://CDS.VizieR/J/AJ/132/1221
Title:
VJHK and SDSS photometry of DA white dwarfs
Short Name:
J/AJ/132/1221
Date:
21 Oct 2021
Publisher:
CDS
Description:
We have calibrated four major ground-based photometric systems with respect to the Hubble Space Telescope (HST) absolute flux scale, which is defined by Vega and four fundamental DA white dwarfs. These photometric systems include the Johnson-Kron-Cousins UBVRI, the Stroemgren uvby filters, the Two Micron All Sky Survey JHKs, and the Sloan Digital Sky Survey ugriz filters. Synthetic magnitudes are calculated from model white dwarf spectra folded through the published filter response functions; these magnitudes in turn are absolutely calibrated with respect to the HST flux scale. Effective zero-magnitude fluxes and zero-point offsets of each system are determined. In order to verify the external observational consistency, as well as to demonstrate the applicability of these definitions, the synthetic magnitudes are compared with the respective observed magnitudes of larger sets of DA white dwarfs that have well-determined effective temperatures and surface gravities and span a wide range in both of these parameters.
17019. VLA A370 Cluster of Galaxies 1.4-GHz Source Catalog
ID:

Title:
VLA A370 Cluster of Galaxies 1.4-GHz Source Catalog
Short Name:
VLA3701P4
Date:
14 Feb 2025
Publisher:
NASA/GSFC HEASARC
Description:
This table contains the 1.4-GHz source catalog for the field of the cluster of galaxies A370 as observed with the Very Large Array (VLA). This is one of the deepest radio images of a cluster field ever taken. The image covers an area of 40&#39; x 40&#39; with a synthesized beam of ~1.7&quot; and a noise level of ~5.7 &micro;Jy (&micro;Jy) near the field center. The authors have cataloged 200 redshifts for the A370 field. In the reference paper, they construct differential number counts for the central regions (radius &lt; 16&#39;) of this cluster, and find that the faint (S&lt;sub&gt;1.4GHz&lt;/sub&gt; &lt; 3 mJy) counts of A370 are roughly consistent with the highest blank field number counts. Their analyses indicate that the number counts are primarily from field radio galaxies. The authors suggest that the disagreement of their number counts for this cluster with those from a similarly deep observation of A2390 that was also presented in the reference paper can be largely attributed to cosmic variance. The authors observed the A370 cluster field with the VLA in the A configuration for ~42.4hr on-source during 1999 August and September. K. S. Dwarakanath observed A370 in the B configuration for ~18.4hr on-source during 1994 August and September. The field center is located at 02:39:32 -01:35:07 (J2000). This is offset by approximately 5 arcminutes from the cluster center at 02:39:50.5 -01:35:08. The authors also targeted 58 radio sources, in A370, that had no existing optical spectral data using the Hydra fiber spectrograph on the Wisconsin-Indiana-Yale-NOAO (WIYN) telescope (spectral window of ~4500 - 9500 Angstrom). They preferentially targeted optically bright galaxies, obtaining these data in a single two-hour pointing on 2012 January 20. Of the 58 targets, the authors obtained high-confidence redshifts for 36. This table was created by the HEASARC in August 2017 based on &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/ApJS/202/2/"&gt;CDS Catalog J/ApJS/202/2/&lt;/a&gt; file table2.dat. This file contained 699 entries for sources detected at 1.4 GHz in the A370 field, as well as 524 entries for sources detected at 1.4 GHz in the A2390 field. Only the former are included in this HEASARC table, while the latter can be found in the HEASARC&#39;s &lt;a href="vla23901p4.html"&gt;VLA23901P4&lt;/a&gt; table.
